My group is trying out 5e so I get to be a player for a bit 
The DM is running Ghosts of Dragonspear Castle and we're using the 6 pregens from that book which he's letting us customize as we level. I've got the human fighter using a sword and board, and the character concept for "Flard Flewyn" somewhat straddles the ranger (for which I picked up the Guide background) and the bard, though without spells.
So in the latest version of the playtest, what would happen if my Level 1 Fighter picked up a level in Bard? Would he become a full-fledged spellcaster?
If that is the case, are there any ways to pick up a second background? Short of pleading the DM?
